Got a 2001 vintage t56. The downshift to 1st and 2nd is becoming difficult. I assuming I have a shift fork/synchro problems. In the scenario I have to pull it out (inevitable) what are opinions on rebuilt kits? Stock, Tick, D&D, ect. Car will make 350-450 hp. Broad range, I know. But I'm not sure my direction yet.
Thanks. All opinions welcome

 

Teardown first. No need to make multiple parts orders if you can call The Gear Box one time.

Although the 3-4 fork is more commonly a problem (if it's aluminum, replace it,) a 1-2 fork issue at the steel link comes up.

Billet keys & bronze pads are popular.

Are you running it behind an LS engine?

 

Yes. Behind a stock ls1 now. May do heads and cam. Trans is first on the list though
